Stack in Queue with process flow

I am trying to make my boxes stack inside the queue using process flow, but there are some errors and I am not sure how to solve this, any idea? Originally, I am planning to have the transporter picks up 1 item at a time from a conveyor, then stack them up in 5 (in the queue). Tried this process flow from some answers in flexsim, but I couldnt figure out where I missed out. Any help would be kindly appreciated. Thanks in advance!

Maybe it's because "token.Stack" is not assigned?

You mentioned "conveyor" from above description, I couldn't find conveyor from your model. My understand is that you want fork load from Queue2, then you simply write "Model.find("Queue2") in first picture, or you could assign token.Stack value in another place like picture2.

For unload action, your original setting also unload to "token.Stack", I assume you would unload to Queue1. Also, make sure the fork should wait until a batch completely arrive, otherwise the work could not pick them up.

Is this what you want? I hope this would help.
